This scanning electron microscope image shows ultrafine diamond needles being pushed on by a diamond tip (dark shape at top). These images reveal that the diamond needles can bend as much as 9% and still return to their original shape. Credit: MIT
Diamonds can be bent and stretched with this new method - short science news

Diamond is the strongest natural material, but it is also brittle, which limits its applications. A team of scientists found a way to make diamonds flexible, opening the door for using this material in new ways. The trick is to convert diamonds into extremely small needle-like shapes which can be stretched like rubber. In a way, these needles behave like the tips of a toothbrush. The results could lead to new diamond-based devices with applications in data storage, electronics, drug delivery and imaging.
